Ugh! It looks like the dreaded Bryopsis algae. Now what?

What should I do here? The below is all of it I see so far. Since it is a newer tank and the frags can be removed, I guess I will take out the rocks and boil them and skim off the top layer of sand (not too hard - it's only a 13 gal AIO tank). I will also clean off the frag plugs. My questions are:
- should I dose the tank with Fluconazole too, just to be sure it's gone? (it only has soft corals in it, no fish yet)
- Are there other things I should be doing other than possibly dosing the tank? I will get a phosphate test kit today but Nitrates are at 0.

-Thanks!

Fluc got rid of it in my tank with no adverse effects.

Easy peasy.....fluconazole. I used it years ago when it was first discussed and had to actually buy the pills and open them up. Works like a charm.

+1 fluc, very effective. May cause diatom/cyano if dieoff is large and not enough microbiome to handle. Will be temporary tho and increased skimming/wc will fix post treatment
